It's like tom brady, he was a pretty accurate passer coming out of college and he was great at coming back cause he had that fierceness about him. You put hi with NE and they started to MOLD their team to his strengths and now he's talked about being GOAT. They have gone thru players left and right and he still does what he does. They've been doing it for years cause they implemented the system and made it work, they've made tweaks here and there but it's the same system he's always been successful at. Same with manning. If you took either QB and thru them into a completely new system they would go from GOAT to above average game managers.

Phillip RIvers is another example. He did great under Norv cause norv tailored to him. You take norv away and i think phillip rivers is a HORRIBLE QB. Bad footwork, horrible mechanics, and weak arm. Unless their new OC is a genius i forsee rivers failing this year just like he has been the last couple.

Barkley can be deadly accurate, he threw so many INT's and his completion % was down a little from having a subpar line, a bad defense, and mediocre running game. Barkley had to force alot of things and put the team on his back quite abit. Like i said he single handled kept them into the oregon and ucla game. His defense was just complete shit

Not to call you out here totally, but lets stop comparing these guys to the best QB's in the game.

Manning and Brady are likely 2 of the best 5 QB's to EVER play. EVER. Lets not start with that.

Barkley isn't deadly accurate. He is accurate, but he doesn't have elite accuracy. He could develop it, sure. But like it has been discussed, Barkley is pretty much topped out mechanically. Changing a little here or there isn't going to make much difference.
